The confidence is an indicator that specifies whether or not the confidence queries matched for a given entity. Evidence scores range from 1 to 7 and give an indication of the amount of content that contributed to the sentiment score. Empirically, the sentiment score is valid if evidence score is equal to or greater than 4.
The formulas which calculate confidence are intellectual property of Lexalytics, and as such are not shared.
